The present invention relates to piping bags or pastry bags and, more particularly, to a dishwasher-safe washing stand for conical bags.
Piping or pastry bags must be cleaned by hand as their lack of rigidity does not allow them to stand inside a conventional or commercial dishwasher. Washing piping or pastry bags by hand is messy, time consuming, and does not allow the bag to be evenly cleaned, thoroughly disinfected, and sanitized. There are no products that allow piping/pastry bags to stand inside a conventional/commercial dishwasher.
As can be seen, there is a need for a means of machine-washing piping or pastry bags.
In one aspect of the present invention, a washing stand comprises an open-ended, truncated cone formed of a dishwasher-safe and food-safe material, having a sidewall with a plurality of evenly spaced apertures therein, wherein the evenly spaced apertures are operative to permit fluid to pass through the sidewall and flow into an article placed over the open-ended, truncated cone.
In another aspect of the present invention, a method of manufacturing the washing stand comprises cutting a sheet of the dishwasher-safe, food-grade material to a predetermined size corresponding to a size of a pastry bag; puncturing the sheet to form the plurality of evenly spaced apertures about 0.25 inch-about 1 inch apart throughout the sheet; rolling the sheet into the open-ended truncated cone, with a first edge overlapping a second edge; and bonding the first edge to the second edge.
With the conventional or commercial dishwasher's water pressure, high heat, and sanitizing capabilities, the support allows the piping/pastry bags to be cleaned, disinfected, and sanitized inside and out, lowering the risk or bacteria forming inside the piping/pastry bag as well as cross contamination of food stuffs. It also enables more than one bag to be washed simultaneously, saving time.
The conical washing stand may also be used to clean and sanitize, in a dishwasher, various items that lack rigidity and fit atop or over the pastry bag support.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description, and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
As used herein, the terms “piping bag” and “pastry bag” are interchangeable.
Broadly, one embodiment of the present invention is an open-ended, truncated cone bag support having a conical sidewall formed with a plurality of evenly distributed apertures.
The double open-ended cone shape enables a piping or pastry bag to stay upright in an open position inside a conventional or commercial dishwasher during a washing cycle so that the inside and outside of the piping/pastry bag may be cleaned simultaneously. The cone is configured and dimensioned to fit inside of a predetermined article, such as a pastry bag.
The evenly distributed holes allow the bag surface facing the cone to be completely and thoroughly cleaned. The holes are operative to permit fluid to pass through the sidewall and flow into an article placed over the support.
The material of manufacture is not particularly limited provided that it is dishwasher-safe and food-safe, and may include, for example, food grade silicone rubber sheet (medium hardness), polypropylene plastic sheet (e.g., with a minimum thickness of about 1/30 inch), and in some embodiments, a suitable adhesive for the sheet used.
The bonding means for forming the truncated cone is not particularly limited. Adhesive or glue may be used in some embodiments, while a different bonding technique may reduce the overlap space needed and/or provide a stronger bond. The bonding technique may form a bonded seam extending along the sidewall from a first open end to a second open end. A preset mold may eliminate the use of adhesive entirely. Moreover, a three-dimensionally (3-D) printed cone may be produced without adhesive and without the use of a hole punch. In these embodiments, the support may be a unitary, injection molded or three-dimensionally printed piece.
A method of making the cone support according to an embodiment of the present invention may include the following steps. Cut a sheet of dishwasher-safe, food-grade material to a predetermined size corresponding to a size of piping/pastry bag. Lay the sheet flat and use a hole punch to punch evenly distributed holes or evenly spaced apertures about 0.25 inch-about 1 inch apart throughout the sheet. Roll the sheet material with punched holes into an open-ended truncated cone shape, leaving approximately a 1-inch overlap for adhesion on each edge, i.e., a first edge overlapping a second edge. To permanently secure the double open-ended cone shape, apply adhesive along the overlap region and allow to dry or cure completely. Thermal bonding may alternatively be used to secure the double open-ended cone shape.
A method of using the cone according to an embodiment of the present invention includes placing a soiled piping/pastry bag over the cone, either with the soiled side facing the cone or inverted to have the soiled side facing outward. Stand the piping/pastry bag with support inside a dishwasher. Let the dishwasher run on a full cycle. Once the cycle is complete, remove the pastry bag with the support from the dishwasher. The clean pastry bag may be separated from the piping/pastry bag, the cone may be used to air dry the piping/pastry bags, and/or the piping/pastry bags may be stored on the cones, allowing them to keep their shape in storage.
